1. Field of the Invention
The present invention relates to a mechanical and/or electronic supercharger simulator. More particularly, the present invention relates to a mechanical and/or electronic supercharger simulator which generates a sound which resembles a race car emanating from a vehicle, for use in both cars and boats to enhance the sound thereof.
2. Description of the Prior Art
Electronic and mechanical devices which produce sound are well known in the art. They range in scope from bicycles to automobiles. However, none are mechanically and/or electronically linked to a motor's rpm.
Numerous innovations for a supercharger/transmission/engine sound duplicator have been provided in the prior art that are described as follows. Even though these innovations may be suitable for the specific individual purposes to which they address, they differ from the present invention as hereinafter contrasted.
In U.S. Pat. No. 4,949,068, titled Motorcycle Sound Simulator for a Child's Toy, invented by John Johnston and Dee Jordan, a device for simulating the sound of a motorcycle as a child's toy in which the simulated sound is composed of at least two rectangular waves partially out of phase with each other, mixed and amplified. The frequency (and preferably the volume) of the mixed rectangular waves varies with the position of a rotatable simulated throttle.
In U.S. Pat. No. 4,875,885, titled Engine Noise Simulating Device for a Bicycle, invented by Horton Johnson, a noisemaker for bicycles and the like includes a housing having a shoulder and a resonator plate seated in the housing on the shoulder. The resonator plate is biased against the shoulder by a compressed spring. A resonator chamber extends from the shoulder, away from the housing. Use of a camming mechanism which raises the resonator plate above the shoulder and releases same as it passes so that the resonator plate is urged back against the shoulder by the spring and a surface-engaging noise and air compression noise are directed into the resonator chamber to simulate the sound commonly associated with a vehicle engine.
In U.S. Pat. No. 4,680,020, titled Toy Vehicle Having Simulated Engine Noise, invented by Melvin R. Kennedy, Dietmar Nagel, and Abraham A. Arad, a free-wheeling toy vehicle which when propelled makes a repetitive sound simulating the noise of an internal combustion engine. The vehicle includes a chassis having bearings supporting front and rear wheel axles. Lying on top of the chassis between the axles is a drum having an elastic drum head. Cantilevered from one end of the chassis is a clapper formed of a flat metal spring terminating in a striker, the spring being biased so that the striker normally rests on the drum head. A finger projects downwardly from the clapper, the tip of the finger being successively engaged by the equispaced teeth of a hub mounted on one of the wheel axles and turning therewith. Each time the finger tip is engaged by a moving tooth, the finger is pushed forward to raise the striker above the drum head; and when the finger then falls between adjacent teeth, the striker is released to hit the drum head to generate a thumping sound. The repetition rate of the clapper action depends on the running speed of the vehicle and therefore acts to create a realistic motor noise.
In U.S. Pat. No. 4,290,054, titled Electrical Apparatus and Method for Electrically Simulating a Noise, invented by Michel Magnani and Moxhel Moulin, an electrical apparatus and method for electrically simulating noise resulting from the thermodynamic expansion of a gas inside a chamber whose volume is varied, is characterized in that it comprises, in series, a capacitor of fixed capacitance and means for varying with respect to time the potential at least one of the terminals of the capacitor, the potential variation depending on the variation of the volume with respect to time and on the nature of said expansion.
In U.S. Pat. No. 2,459,860, titled Engine Noise Equipment, invented by Claude K. Wilkinson, this invention relates to a noise maker and has for an object to provide an improved noise maker especially adapted for simulating the noise made by an engine or motor in operation, particularly that produced by an aircraft motor.
The above patented inventions differ from the present invention because the lack one or more features of the following described and claimed in the present invention: mechanical supercharger simulator housing having a mechanical supercharger simulator housing egress port and a mechanical supercharger simulator housing ingress port, a mechanical supercharger simulator shaft which comprises a plurality of mechanical supercharger simulator flexible fins longitudinally disposed thereon, an electronic supercharger/transmission/engine sound duplicator microprocessor, an electronic supercharger/transmission/engine sound rpm sensor, an electronic supercharger/transmission/engine sound speaker, an electronic supercharger/transmission/engine sound switch, an electronic supercharger/transmission/engine sound volume control, electronic supercharger/transmission/engine sound trim adjuster, and vacuum sensor.
Numerous innovations for a supercharger/transmission/engine sound duplicator have been provided in the prior art that are adapted to be used. Even though these innovations may be suitable for the specific individual purposes to which they address, they would not be suitable for the purposes of the present invention as heretofore described.
The present invention relates to a mechanical and/or electronic supercharger simulator. More particularly, the present invention relates to a mechanical and/or electronic supercharger simulator which generates a sound which resembles a race car emanating from a vehicle, such as the mechanical whine of a gear train from a high performance transmission, or such from a gear train of rotors of a type positive displacement blower or supercharger.
The types of problems encountered in the prior art are engines produced are so muffled for sound and pollution that the awesome sounds of the vehicles of yesteryears are not present in today's cars.
In the prior art, unsuccessful attempts to solve this problem were attempted namely: reducing muffling and back pressure. However, the problem was solved by the present invention because the heightened muffling and back pressure can remain while still emanating an awesome sound of yesteryears sound.
Innovations within the prior art are rapidly being exploited in the automotive field.
The present invention went contrary to the teaching of the art which teaches reduced muffling and back pressure.
The present invention solved a long felt need for a mechanical and or electronic supercharger/transmission/engine sound duplicator which is linked to a motor's rpm.
Accordingly, it is an object of the present invention to provide a supercharger/transmission/engine sound duplicator which comprises a mechanical supercharger simulator housing having a mechanical supercharger simulator housing egress port and a mechanical supercharger simulator housing ingress port.
More particularly, it is an object of the present invention to provide a supercharger/transmission/engine sound duplicator which comprises a mechanical supercharger simulator shaft which comprises a plurality of mechanical supercharger simulator flexible fins longitudinally disposed thereon.
In keeping with these objects, and with others which will become apparent hereinafter, one feature of the present invention resides, briefly stated, in a supercharger/transmission/engine sound duplicator which comprises an electronic supercharger/transmission/engine sound duplicator microprocessor and amplifier.
When the supercharger/transmission/engine sound duplicator is designed in accordance with the present invention, it further comprises an electronic supercharger/transmission/engine sound rpm sensor.
In accordance with another feature of the present invention, the supercharger/transmission/engine sound duplicator further comprises an electronic supercharger/transmission/engine sound speaker.
Another feature of the present invention is that the supercharger/transmission/engine sound duplicator further comprises an electronic supercharger/transmission/engine sound switch.
Yet another feature of the present invention is that the supercharger/transmission/engine sound duplicator further comprises an electronic supercharger/transmission/engine sound volume control.
Still another feature of the present invention is that the supercharger/transmission/engine sound duplicator further comprises an electronic supercharger/transmission/engine sound trim adjuster.
The novel features which are considered characteristic for the invention are set forth in the appended claims. The invention itself, however, both as to its construction and its method of operation, together with additional objects and advantages thereof, will be best understood from the following description of the specific embodiments when read and understood in connection with the accompanying drawings.
